corporation of New Jersey Application February 10, 1933. Serial No. 656,16"?

4 Claims.

This invention relates to strippers for Toscani cigar machine pasters, its main object being to overcome the trouble which developed in previous machines when the paster member was lifted from the wrapper. In previous Toscani cigar machines the paster member when being lifted from the wrapper, frequently carried the wrapper along with it, thus altering or otherwise disturbing the original position of the wrapper on the rolling apron. The wrapper thus shifted on the rolling apron resulted in imperfect wrapping of the cigar.

In the present invention, this object is achieved by providing the paster with a stripper, its vertical portion extending beyond the base of the paster, when the unit is in its inoperative position. Therefore when the unit descends upon the rolling apron the vertical portion of the stripper bears against the wrapper, thus applying a patch of paste to the same. The paster then ascends, the stripper remaining relatively stationary in respect to the wrapper, until the paster has separated from the wrapper. The continued ascent of the paster finally engages the horizontal arms of the stripper thus lifting the same from the Wrapper. The wrapper being held in this manner remains in its original position on the rolling apron, thus assuring a perfectly rolled cigar. With this and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawing which forms a part of this specification and in which like characters of reference indicate the same or like parts:

Fig. 1 is a partial plan view of the cigar machine showing the arrangement of the paste applying unit;

Fig. 2 is an end view taken on line 22 of Fig. 1, showing the stripper engaging the wrapper; and

Fig. 3 is an end view of the same showing the paster in its down position.

In carrying the invention into effect there is provided a paste pot, a paste roller mounted in said pot. a paste carrying member, means for moving said member over said roller to receive paste from the roller and into engagement with a wrapper to apply the paste thereto, and a device for stripping the wrapper from said member. In the best forms of construction contemplated said means includes a pedestal, a shaft reciprocably F mounted in the pedestal and free to turn therein,

an arm fixed to said shaft, and a plate connected to said arm, said device including a stripper pivotally mounted on said plate, and said paste carrying member being connected to said arm. These various means and parts may be widely varied in construction within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific construction shown and described.

Referring to the drawing, the bed 10 of the machine carries a paste pot 11, supporting a shaft 12 on which is mounted a paste roller 13. In a pedestal 14 attached to the bed 10 is reciprocably mounted a vertical shaft 15 carrying an arm 16, the other end of the arm 16 carrying a stud 17 attached to a bar 18. To the bar 18 is attached a paste carrying member 19 formed of a piece of sponge rubber. The bar 18 also carries a plate 20. The projecting ends of plate 20 are looped to receive a stud 21 which carries the horizontal arms 22 of the stripper 23. The upward extending arm 24 of stripper 23 carries a stud 25 on which is mounted a roller 26. The arm 16 carries a bracket 27 attached to which is a leather piece 28.

A wrapper W is cut from a leaf, and transferred from the wrapper cutting-bed to a wrapper carrier (not shown), and by the latter transferred to a rolling apron 29 which lies over a rolling table 30 of usual construction. Referring to Patent 1,536,330 issued May 25, 1926 to R. E. Rundell, the transferring of the wrapper, and the hereinafter mentioned motions of the arm 16 will be clearly understood, reference to the aforesaid patent being made for a complete disclosure of mechanism for actuating the shaft 15 to oscillate and reciprocate the arm 16. The wrapper being thus positioned on the rolling apron 29 the arm 16 swings from its paste receiving station to a position over the wrapper W. Arriving at its latter position the arm 16 descends and the stripper 23 engages the wrapper W as shown in Fig. 2. The continued descent of the arm 16 permits the paste carrying member 19 to rest against the wrapper W as shown in Fig. 3. The wrapper thus being pasted along its edge, the arm 16 ascends, the stripper 23 remaining relatively stationary in respect to the wrapper and holding the same, thus preventing the wrapper from being carried along by the paster 19. The stripper remains engaged with the wrapper until the ascending bar 18 engages the horizontal arms 22, the continued upward motion of arm 16 carrying the entire unit from the wrapper W.

The arm 16 is now swung towards the paste pot 11 and in so doing, the roller 26 engages the circular shaped cam piece 31 attached to the paste pot 11, which lifts the pivotally mounted stripper 23 out of the path of roller 13. The swinging of arm 16 also permits the leather piece 28 to engage the wheel 32 thus turning the paste roller 13. In this manner, the paster member 19 passes over the revolving roller 13 and picks up a quantity of paste sufficient for the next wrapper,

What is claimed is:

1. In a cigar machine paster, the combination with a paste pot, of a paste roller rotatably mounted in said pot, a paste carrying member, means for moving said member over said roller to receive paste from the roller and into engagement with a wrapper to apply the paste thereto, and a device for stripping the wrapper from said member, said means including an oscillatory shaft, an arm on said shaft, and a leather piece secured to and hanging freely from said arm, said member being connected to said arm, and. said roller having a shaft projecting from said pot and provided with a pulley on said projecting end arranged to be engaged by the leather piece on said arm while the latter is swung over said pot and thereby rotate said roller.

2. In a cigar machine pastel, the combination with a paste pot, of a paste roller rotatably mounted in said pot, a paste carrying member, means for moving said member over said roller to receive paste from the roller and into engagement with a wrapper to apply the paste thereto, and a device for stripping the wrapper from said member, said means including a pedestal, a shaft reciprocably mounted in said pedestal and free to turn therein, an arm fixed to said shaft, and a plate connected to said arm, said device including a stripper pivotally mounted on said plate, and a cam roller carried by said stripper, and said pot having a cam piece mounted thereon and arranged to engage said cam roller when said arm is swung over said pot to raise said stripper above the pot.

3. The combination with a pedestal, of a shaft reciprocably mounted in said pedestal, an arm carried by said shaft, a plate and a paste carrying member connected to said arm, and a stripper pivotally mounted on said plate.

4. In a cigar machine, the combination with a support for holding an outspread tobacco leaf, a paste applying element, mechanism for giving said element movement to and from paste applying position in contact with said leaf, a stripper, and means yieldingly urging said stripper against the leaf as said element moves away from paste applying position to prevent the leaf from following said element.
